ActionScript 2.0 :: Get The Datatype Of A Variable?

How do I get the datatype of a variable? In this case it is pretty obvious, but I am trying to make a substitute for function overloading in a class.

I have to convert one string type field to date datatype in flex.
View 3 RepliesThrough an XMLSocket, I get a basic datatype as a String value, such as "int", "String", "Array", etc... I would like to instantiate a new variable of the specified datatype. Something along the lines of the following psuedocode:
Code:
function createVariable(type:String, value:*):void
{
var dataTypeRef:* = getDataTypeRef( type ); [code]......
is there a method to return the datatype of a variable?
View 3 Repliesi'm working on converting an Action Sript class to C# and now i'm choosing a proper data types to replace ActionScript data Types ... and i wondered what is the best C# datatype to replace the Dictionary Datatype in Actionscript here's a sample code for example
public static const db:String = "http://dbpedia.org/resource/";
public static const rdf:String = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
public static const skos:String = "http://www.w3.org/2004/02/skos/core#";
[Code].....
so as my title says. I'm wondering if specifying the datatype in actionscript 3 on variables actually makes code run faster

View 5 Repliesbasically what I am trying to do is dynamically add graphics using actionscript. So far it has worked but I ran into a problem. I am using addChild to add the pictures and the instance name.addChild(imageLoader). I need to convert the xml parsed data (xmlData.player[0].@position) to a instance name which I believe is data type MovieClip. So I am trying to convert my xml which is a string to a movieclip. Here are snippets of code:
var position:MovieClip = XmlData.player[0].@position; //Doesn't workgives Error #1034: Type Coercion failed: cannot convert XMLList@1f2d2e09 to flash.display.MovieClip.
var position:String = XmlData.player[0].@position; //Does work

Has anyone implemented a Set class in ActionScript? Specifically, a Set which is similar to Python's set implementation (unordered, unique, O(1) membership, etc). I'd like to be able to iterate over it using for each, perform operations like union and intersection and get a list of all the contained items... Which would all be possible to implement using Dictionary and Proxy, but I'd rather not reimplement it if someone's already done the heavy lifting.

View 3 RepliesThe title of this post may not make much sense, let me explain. I have a function:
findSurface(origin:Point, vector:Point, attempts:Number):Point The function has an obscure use, but the idea is thus: given those three arguments, returns a point IF the 'line' (created by the origin and vector arguments) intersects the object the function is called on. [but that is another story...]
More importantly, if there is no point of intersection at all, what should the function return? Void? Null? Undefined? Object? Or can I use one of those return types instead of Point incase the function does not encounter an intersection?
is there a way to convert dynamicly?
that's the default way to convert a String:
var toVal:* = int("5");
var toVal:* = Boolean("true");
but I wan't to do this:
var type:String = "int";
var toVal:* = type("5"); // <<<<< how can I do this
I am trying to run an if statement based on the a variables datatype
var theArray:Array = ['element1','element2'}];
var theString:String = "I am string";
trace(gettype(theArray));
// In php gettype() is what I use to get the type. Is there a similar function in as3?
How exactly does the datatype checking of Vector work? The documentation states that an exception occurs at runtime if there was a wrong argument pushed to the Vector. However if I try this:
Code:
private var numberVector:Vector.<Number> = new Vector.<Number>();
...
numberVector.push(thumbnailInstance)
And then I trace it, I get NaN (cos it is a thumbnail ). However, no exception is being thrown.
What's happening in this simple piece of AS3 code? Why does my object change from TextField to the more generic DisplayObject?
public class Menu extends MovieClip
{
private var active_button:SimpleButton;
public function Menu()
{

I have been following the samples code of Foundation ActionScript 3.0.
I have imported a jpeg into Flash CS3 IDE Library and Exported(Linkage) it to be used in action script by giving a class name 'Image'. And when I am trying to compile the file its showing error: 1136: Incorrect number of arguments. Expected 2. and 1067: Implicit coercion of a value of type Image to an unrelated type flash.display:Bitmap.
How to attach the jpeg to the stage as a Bitmap datatype using as3..

can I use the Class datatype to make a class a property, then create new objects from that class? Like so:
class Foo{
private var ExampleClass:Class;
public function Foo(exampleClass:Class){
[Code]....
f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".

I'm trying to pass the contents of variable playnoyes to the long line of code below to decide whether or not to autoplay the flash movie, but doing it as I have below, the resultant line of code has the variable in quotes and therefore the code doesn't execute it as expected. My question is, how can I pass the variable so that the resulting line of code doesn't have the quotes around the variable value.
var playnoyes='true';

I want to declare a variable on the main timeline that can be called from anywhere in my movie. So, _global var should be the right approach. I want to declare a movie clip 'MC1' "open", or "closed" so that when it is revisited, my flash file knows the user has been there before and performs a different task from the one it does when 'MC1' was first encountered. So, i need a 'if' statement to run from the variable, when the playhead encounters the movieClip.

I have 2 movie clips, one being loaded into a container MC via "loadMovie();"In the main movie there is a variable with no value, in the external movie there are 5 frames, each with a value to update the variable in the main movie.
IE: if on frame 1, global value = 1 / if on frame 2, global value = 2 / etc etc I'm familiar with passing variables INTO an external swf, but am stumped on how to do it the reverse way.
var loader:Loader = new Loader();
loader.load(new URLRequest("panghat spa.swf"));
addChild(loader);
want to load panghat spa.swf as a variable by pasing variable from html page in to flash
I'm still learning flash and actionscript 3 and i am having trouble with variable and object names. I need to be able to combine variable names together (in the same way as php can combine by doing var1.var2).
My swf contains 4 loaders (image1_loader, image2_loader etc..) which are a child of (image1_content, image2_content etc.....)
I then have 4 buttons which load an image into the loader and while doing so they define the currently active loader.
Finally i have 4 control buttons - scale up/down and rotate clockwise/anticlockwise which should only control the currently active loader (as set by the buttons above)[code]...
